Ichigen

Ichigen (一見) was a young monk-in-training at the Fire Temple.

Personality

He deeply admired Chiriku and aspired to be like him.

His young age and unfinished training meant that his skills were still immature.

It was Ichigen who warned Chiriku of the intruding Akatsuki members Kakuzu and Hidan.

He is presumed to be dead since he isn't identified as one of the three known monk survivors in the temple attack.
